How can I automate an Issue Custom Field when the Rank of an Epic is changed?

Question

I have 2 boards: one displays only Epics, and the other displays only Issues. The Epic Board is ordered by Rank, so I use drag-and-drop to arrange them. I would like to update a Custom Field that I created, called "Epic Order," when I reorder Epics using drag-and-drop. Additionally, I'd like this field to be replicated to all Stories associated with the Epic that was reordered, in such a way that the Story Board is automatically reordered when I change the order of the Epics.

The problem is that I can't find the "Rank" field when searching for it in the automation feature. Is there a way to copy this field to a custom field?

That field would not be human-readable...and copying it would likely break things: the rank value for each issue in a site is unique.

Repeating my earlier ideas:

* The REST API function is needed to programmatically update the rank field
* Please discuss what you are trying to do with your Jira site admin for their input

Hello! Thanks for your reply.
I'm trying to find this field called "Classification", that is our Global Rank field

On the "Issues" screen, I'm able to find the field and see the data

Thank you for the advice. I'm not entirely sure if I understood everything correctly, but what I need to do is copy the "Lexorank" field of the Global Rank to another alphanumeric custom field and replicate it for all Stories within an Epic. However, I'm having trouble finding a way to copy the data from the Rank field.

That's the field.

I can see it in the "Issues" screen.

But I can't find it in the automation fields.
